Hey guys, I've just tried to downgrade my HBOOT from 0.83.0001 to 0.80 using the .zip file method on XDA forums, and I booted into HBOOT, it recognised the .zip and asked me if I wanted to install so I selected yes, then the progress thing came up but the screen just went suddenly blank after about a second. I left it for about 10-15 minutes but when I came back to it the screen was still blank, so I took out the battery to reset it. Now, when I turn on the phone it vibrates once, but nothing appears on the screen, although it is detected by USB. tl;dr - Phone vibrates when turned on but nothing on screen. Phone is still detected by USB. Is it essentially bricked? I tried to use RUU, Error 140 Bootloader error. If it's bricked it's not the end of the world I only bought it two days ago and can play it off as faulty lol. Cheers for any enlightenment you may be able to offer me.
